When it comes to rectal bleeding, everyone still feels very scared. Because the most obvious symptom of rectal cancer is bleeding in the stool, but it is not only rectal cancer that can cause bleeding in the stool. Hemorrhoids and anal fissures can also lead to bloody stools. Therefore, we still need to first understand the specific reasons for fecal bleeding. Next, let's take a look at what causes fresh red blood in the stool?
1. Hemorrhoids
Hemorrhoids are one of the common causes of rectal bleeding, and internal hemorrhoids are the most common cause of rectal bleeding. Hematochezia caused by internal hemorrhoids generally does not cause pain, and severe anal pain symptoms only occur when the hemorrhoids protrude from the anus. Hematochezia is bright red in color and mostly appears after defecation. If excessive force is applied during defecation, it may damage the mucosa in the cecum, causing an increase in intravascular pressure and resulting in jet bleeding in patients.
2. Anal fissure
Unlike rectal bleeding caused by hemorrhoids, in addition to bloody stools, the main characteristic of rectal bleeding caused by anal fissures is severe pain around the anus, especially during defecation, which is extremely painful. This intense pain usually takes several minutes to subside, but that's not all. If there is a spasm of the anal sphincter after defecation, this intense pain will occur again and last for several hours or even more than ten hours. The main reason for this is that anal fissures can make the skin of the anal canal particularly fragile and ulcerated, which can easily cause severe pain. During defecation, hard feces can repeatedly rub against the ulceration and fragile skin, leading to severe pain.
3. Various enteritis
Due to inflammation, the integrity of the intestinal mucosa is disrupted, resulting in the presence of dark purple blood and secretions mixed in the stool, accompanied by various symptoms unique to enteritis. Experts remind that in addition to the two common causes mentioned above, there are many complex factors that can cause rectal bleeding. Therefore, when rectal bleeding occurs, the best way is to go to the hospital for examination and diagnosis, and receive targeted treatment to get rid of the trouble of rectal bleeding as soon as possible.
The above is the relevant content about what causes fresh red blood in stool bleeding. In short, the possibility of rectal diseases is highest when the stool bleeding is bright red. In order to eliminate the psychological shadow of patients, it is recommended that everyone actively go to the hospital for examination and treatment. No matter what kind of disease it is, as long as it is treated in a timely manner, it will be cured. I hope this article can be helpful to everyone!
